Application led November 2, 1915. Serial No. 59,217.

To all 'whom t may Gomera.' l

Be .it known that 1, O'rro Zanini, -a citizen of the United States, andresident of Aurora, county of Kane, and State'oi' Illinois, haveinvented certain new and useful Improvements in "Vehicle-Wheel Hubs, ofwhich the :following is a specification, and which| are illustrated inthe accompanying drawings, forming a part thereof.

The invention relates to hubs for vehicle wheels, and is especiallyadapted for service in wheels having wire spokes and, as to somefeatures of the invention, it is capable of use in the rebuilding of oldwheels, retaining the inner section of the original hub.

The invent'on consists of a structure such as is herona er described.und as illustrated in the accompanying drawings, ,in Which- Figure 1isf'a sectional View on the line 1.1 of Fig. 3;

Fig-2 is an end View o the hub, with a portion of the dust guard brokenaway;

Fig. 3 is a rear elevation of the hub;

Fig. #l is a froiit viewl of the hub, partly broken away and showing amodified form of construction;

Fig. 5 is a longitudinal section. of the hub shown in Fig. 4.; and

Fig. 6 is an inside` elevation of the same hub.

The improved hub is intended more especially for use on automobiles. Asillustrated in Figs. 1 and 3, it is applicable to the 'forward wheels oia vehicle, and as illustrated in Fig. 5 it is. 'iiitended for use on alive axle and hence :it the rear oi the vehicle.

Referring: to Fig. l. the element 1() is the shell. constitutingr thecentral member of the hub and adapted to receive and run upon a fixed ordead axle; boing provided with ball bearings for this purpose. as shown.This element may be either a part of an entirely new hub, or it may havebeen the central or sleeve member oi an old huh from which the woodenspokes have heen removed. It is provided with the usual radial flange 11at 4its inner end. A

Upon the sleeve 10 there is fitted a shell' 12, having atits inner endan instanding` the forward or outer end of the shell there is providedan annular outstanding flange 1:3 and a circumferential flange 16extending forwardly therefrom. In line with, and forming a continuationof the flange 15, there is an instandingJ flange 17 within which theinner end of the hub cap 18 may enter for engagement by suitable threadswith the sleeve 10. Preferably the huh cap fits snugly within the flange10, and thus forms an outer bearing for the shell 12. The hub cap isprovided with an outstanding liange 19, adapted to bear against theouter face of the flange 17, and is provided on its periphery withratchet teeth 20.

A pawl 21, pivoted to the flange 15, coperates with these ratchet teeth,and is normally held in engagement ltherewith by means of a spring 22reacting against the flange 16.- A pull rod 2.3, attached to thel pawl,extends through a suitable aperture in the flange 1G, and provides meansfor lifting the paw] out of engagement with the ratchet teeth to permittho hub cap to be rerlioved from the sleeve 10. A dust cap 24, hereshown :is a separate element, fits tightly upon the outer end of the hubcap and overlaps the fange 16.

At the tnner end of the shell 12 there is an outstandingI flange 27, andWithin the flange 16 and the flange 2 7 there are 'formed suitableapertures, as 25, 26, 28 and 29, for

the reception of the inner ends of the wire' spokes.

ln the construction illustrated in Figs. et and 5, the pawl 30 forcoperatingr with the ratchet teeth 20 is provided with a rearwardprojection 31, to which pressure may be applied for raising the nose ofthe pawl. ln lieu of the pull rod 23 a removable pushrod 32 is employed,a suitable aperture be# ing provided in the flange 16 for its reception.For convenience this push-rod may be provided with :i laterulvlug 33,which will hold the rod against dutward m vement after it has beeninserted to dsem age the pa'wl and given a quarter turn.

The inner hub sleeve 34, shown in Figs. 5 and 6, is adapted to fitsnugly upon and he keyed to an axle. The shell 35 dillers "from theshell 12 in that itis provided with an eccentric recess in its innerface to le eeive the radial flange 36 of the sleeve, this yflange beinggiven a compl@mentarir form in order that it may fit tightly within therecess and thus prevent relative turning movement of' the sleeve andshell. The hub cap 37, illustrated in Fig. 5, is substantially of thesame form as the hub cap 18, except n that the dust guard 38 is formedlintegral therewith. 4

At 39 there is shown a portion of a brake drum usually eniployed withthe rear Wheels of an automobile, and it may be attached to the hub inanysuitable manner, as by screws Ll() setting through the Iflange 36.

While preferred embodiments of the invention are shown, various changesmay be made 'without departing from its scope.

l claim as my invention l. In a vehicle hub, in combination, a sleeveadapted to receive a shaft and having a radial flange, a shell inclosingthe sleeve and having an instanding annular flange for bearingthereupomthe shell being locked to the sleeve flange to prevent relativerotation of' the parts, and a cap in threaded engagement with the Sleeveand bearing longitudi- 1 nally on the shell.

:2. In a vehicle hub, in combination, a sleeve adapted to receive ashaft and having la radial flange, a shell inelosing the sleeve andbeing locked to the flange thereof tol Vbearing on the cap, and a secondinstanding annular flange bearing on the sleeve.

' 4. ln a vehicle hub, yi1ini-fcogmloination a sleeve adapted to receivea ehaftand having an eccentric radial-fiangefavshell inclosing andconcentric with the ell-,9re and fitting snugly on the eccentric* nge,such shell having an instanding .annular flange 'hear' ing `on thesleeve, anda second lnstanding annular. flange, and a cap inthreadedeil--v thread, a shell inclosing the sleeve and sel cured to itsflange and having at'its outer .i end a radial face and a forwardlyprojecting circumferential flange, a cap in threaded engagement with thesleeve and having an annular series of ratchet teeth, a spring pavrlpivotally secured to the radial face of the shell and eoperating withthe ratchet teeth, a pull `rod attached to the .pawl and extend ingthrough the circumferential ange of theshell, and a platecarried by thecap and fitting against the end of the circumferential flange. A

` 6. vIn a Wheel hub, in combination, a sleeve having a radial flangeand an external thread, a shell inclosing the sleeve and secured to` itsflange and having at its outer end a radial face and a forwardlyproject- 'ing circumferential flange, a cap in threaded engagement withthe sleeve and having anl annular series of ratchet teeth, a spring pawlpivotally secured to the radial face of the shell and coperating withthe ratchet teeth, a rod for controlling the pawl" extending' throughthe circumferential flange of the shell, and a plate carried by the capand fitting against the end of the circumferential,

flange.
